I want to activate AHK-functions, triggered when my soundcard plays any sound.

There is no other way to detect if a special event takes place. The one and only indicator is a "build in" sound from another program.

PLEASE can anybody help me to solve this problem?

Tank you!

as far as i know, there's no neat way to do this unless dealing in the driver level.
here's the trick.

1) capture sound by using MixMP3
2) record with silence filter (read help of mixmp3)
3) check output file size consistently.
4) if it's over 16.1kb (16.0kb is minimal) sound is playing.

Example (Mixmp3.exe need to be in same directory)

Someone might extract something usefull from this: [audio-input-output-level], hopefully.
